Pink silk halter-necks have been worn and treasured by Vietnamese women over the last century and are still considered an integral part of their traditional costume today.
More than 100 years ago, the yem tham became a fashion item that symbolised the Vietnamese women's desire to make themselves more beautiful. The halter-neck and silk ties at the back of the garment are pulled tight to accentuate the delicate figure of Vietnamese women, and most importantly to create the concave effect of the "wasp waist".
